Introduction: Kaineng Company was founded in 1857 by Mathias Klein, a hardworking German immigrant. When he first entered the tool industry, a telegraph line repairman went to Mathias Klein's blacksmith's shop with a damaged side cutter to repair it. Mathias Klein personally forged and polished the damaged part of the pliers into a new half, and then riveted it to the old half. Soon after, the line repairman came back with this side cutting pliers for repair, because the old half of the pliers body was damaged and needed to be replaced. Mathias Klein re forged and polished the old half into a new one, and then riveted it to the previously repaired half, giving birth to the first complete Kaineng tool pliers. To this day, his family members proudly inherit and manage the Kaineng Tool Company. After more than 150 years of continuous efforts and dedication, we have won high praise from users. Kaineng Tool Company only provides users with the highest quality professional manual tools and occupational protection devices.
